    6 units

    Step-by-step explanation:

    Since you're familiar with your times tables, you know that 6*9 = 54. Since the area is the product of length and width, these numbers could be the length and width of the rectangle.

    We notice that 9 is 3 more than 6, so corresponds to the requirement for length. Then the width of the rectangle is 6 units.
